further. Decrease this value if recognition is taking too long. To adjust trailing silence, tap and

drag the thumb of the Maximum trailing silence slider to the desired position. Alternatively,

you can tap the thumb and use the navigation pad to scroll the thumb along the slider. The

default value is 0.5 seconds.
